| Abstract: | In this paper, effects of leaf nitrogen content and LAI in different stages on the growth and yield in early rice,and relation of the dry matter production after flowering to filled spikets percentage were analyzed through the simulation of the rice growth and yield by rice growth simulation model,ORYZA1 in jiangxin city.Zhejiang province in 1992. Simulated yields a-gree well to actual one. The possibility of the application of the model in estimating rice yield in combination with remot scensing was discussed. |
